When list_for_each_entry() completes the iteration over the whole list
without breaking the loop, the iterator value will be a bogus pointer
computed based on the head element.
While it is safe to use the pointer to determine if it was computed
based on the head element, either with list_entry_is_head() or
&pos->member == head, using the iterator variable after the loop should
be avoided.
In preparation to limit the scope of a list iterator to the list
traversal loop, use a dedicated pointer to point to the found element [1].

In preparation to limit the scope of a list iterator to the list
traversal loop, use a dedicated pointer to iterate through the list [1].
Since that variable should not be used past the loop iteration, a
separate variable is used to 'remember the current location within the
loop'.
To either continue iterating from that position or skip the iteration
(if the previous iteration was complete) list_prepare_entry() is used.

Pull random number generator fixes from Jason Donenfeld:
- If a hardware random number generator passes a sufficiently large
chunk of entropy to random.c during early boot, we now skip the
"fast_init" business and let it initialize the RNG.
This makes CONFIG_RANDOM_TRUST_BOOTLOADER=y actually useful.
- We already have the command line `random.trust_cpu=0/1` option for
RDRAND, which let distros enable CONFIG_RANDOM_TRUST_CPU=y while
placating concerns of more paranoid users.
Now we add `random.trust_bootloader=0/1` so that distros can
similarly enable CONFIG_RANDOM_TRUST_BOOTLOADER=y.
- Re-add a comment that got removed by accident in the recent revert.
- Add the spec-compliant ACPI CID for vmgenid, which Microsoft added to
the vmgenid spec at Ard's request during earlier review.
- Restore build-time randomness via the latent entropy plugin, which
was lost when we transitioned to using a hash function.

Prior, the "input_pool_data" array needed no real initialization, and so
it was easy to mark it with __latent_entropy to populate it during
compile-time. In switching to using a hash function, this required us to
specifically initialize it to some specific state, which means we
dropped the __latent_entropy attribute. An unfortunate side effect was
this meant the pool was no longer seeded using compile-time random data.
In order to bring this back, we declare an array in rand_initialize()
with __latent_entropy and call mix_pool_bytes() on that at init, which
accomplishes the same thing as before. We make this __initconst, so that
it doesn't take up space at runtime after init.

====================
pull-request: can 2022-03-31
The first patch is by Oliver Hartkopp and fixes MSG_PEEK feature in
the CAN ISOTP protocol (broken in net-next for v5.18 only).
Tom Rix's patch for the mcp251xfd driver fixes the propagation of an
error value in case of an error.
A patch by me for the m_can driver fixes a use-after-free in the xmit
handler for m_can IP cores v3.0.x.
Hangyu Hua contributes 3 patches fixing the same double free in the
error path of the xmit handler in the ems_usb, usb_8dev and mcba_usb
USB CAN driver.
Pavel Skripkin contributes a patch for the mcba_usb driver to properly
check the endpoint type.
The last patch is by me and fixes a mem leak in the gs_usb, which was
introduced in net-next for v5.18.

The previous commit fixed a memory leak on the send path in the event
that IPv6 is disabled at compile time, but how did a packet even arrive
there to begin with? It turns out we have previously allowed IPv6
endpoints even when IPv6 support is disabled at compile time. This is
awkward and inconsistent. Instead, let's just ignore all things IPv6,
the same way we do other malformed endpoints, in the case where IPv6 is
disabled.

We make too nuanced use of ptr_ring to entirely move to the skb_array
wrappers, but we at least should avoid the naughty function pointer cast
when cleaning up skbs. Otherwise RAP/CFI will honk at us. This patch
uses the __skb_array_destroy_skb wrapper for the cleanup, rather than
directly providing kfree_skb, which is what other drivers in the same
situation do too.

Scenario:
---------
bio chain generated by blk_queue_split().
Some split bio fails and propagates its error status to the "parent" bio.
But then the (last part of the) parent bio itself completes without error.
We would clobber the already recorded error status with BLK_STS_OK,
causing silent data corruption.
Reproducer:
-----------
How to trigger this in the real world within seconds:
DRBD on top of degraded parity raid,
small stripe_cache_size, large read_ahead setting.
Drop page cache (sysctl vm.drop_caches=1, fadvise "DONTNEED",
umount and mount again, "reboot").
Cause significant read ahead.
Large read ahead request is split by blk_queue_split().
Parts of the read ahead that are already in the stripe cache,
or find an available stripe cache to use, can be serviced.
Parts of the read ahead that would need "too much work",
would need to wait for a "stripe_head" to become available,
are rejected immediately.
For larger read ahead requests that are split in many pieces, it is very
likely that some "splits" will be serviced, but then the stripe cache is
exhausted/busy, and the remaining ones will be rejected.

rpmsg devices to acquire pointers to memory shared with the remote
processor.
The TI K3 R5F and DSP drivers gains support for attaching to instances

The Mediatek remoteproc driver gains support for the MT8186 SCP. The
driver's probe function is reordered and moved to use the devres
version of rproc_alloc() to save a few gotos. The driver's probe
function is also transitioned to use dev_err_probe() to provide better
debug support.
Support for the Qualcomm SC7280 Wireless Subsystem (WPSS) is

voting for interconnect bandwidth during launch of the remote
processor. The modem subsystem (MSS) driver gains support for probing
the BAM-DMUX driver, which provides the network interface towards the

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"There's one large change in the core clk framework here. We change how
clk_set_rate_range() works so that the frequency is re-evaulated each
time the rate is changed. Previously we wouldn't let clk providers see
a rate that was different if it was still within the range, which
could be bad for power if the clk could run slower when a range
expands. Now the clk provider can decide to do something differently
when the constraints change. This broke Nvidia's clk driver so we had
to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk
framework that we're going to extend in the next release. It already
made it easy to find corner cases in the rate range patches so I'm
excited to see it cover more clk code and increase our confidence in
core framework patches in the future. I also added a kunit test for
the basic clk gate code and that work will continue to cover more
basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and
additions. Qualcomm again dominates the diffstat here with lots more
SoCs being supported and i.MX follows afer that with a similar number
of SoCs gaining clk drivers. Beyond those large additions there's
drivers being modernized to use clk_parent_data so we can move away
from global string names for all the clks in an SoC. Finally there's
lots of little fixes all over the clk drivers for typos, warnings, and
missing clks that aren't critical and get batched up waiting for the
next merge window to open. Nothing super big stands out in the driver
pile. Full details are below.
Core:
- Make clk_set_rate_range() re-evaluate the limits each time
- Introduce various clk_set_rate_range() tests

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The update for this cycle includes the deprecation of block-aperture
mode and a new perf events interface for the papr_scm nvdimm driver.
The perf events approach was acked by PeterZ.
- Add perf support for nvdimm events, initially only for 'papr_scm'
devices.
- Deprecate the 'block aperture' support in libnvdimm, it only ever
existed in the specification, not in shipping product"

Support for cryptoloop was deleted in commit 47e9624616c8 ("block:
remove support for cryptoloop and the xor transfer"), making the usage
of loop_info->lo_encrypt_type obsolete. However, this member was also
removed from the compat_loop_info definition and this breaks userspace
ioctl calls for 32-bit binaries and CONFIG_COMPAT=y.
This patch restores the compat_loop_info->lo_encrypt_type member and
marks it obsolete as well as in the uapi header definitions.
Fixes: 47e9624616c8 ("block: remove support for cryptoloop and the xor transfer")
